STEM-WINDING AND SETTING MECHANISM FOR WATCHES.

EPECIPICATION forming part of Letters Patent No. 338,945, dated March 30, 1886.

Application filed October 3, 1885. Serial No. 178,934.

To all whom it may concern:

Be it known that I, WALTER H. Frrz GER- ALD, of Brooklyn, in the county of Kings, and in the State of New York, have invented certain Improvements in Stem Winding and Setting atches; and I do hereby declare that the followingis afnll, clear, and exact description thereof, reference being had to the accompanying drawings, in which- Figurel is an enlarged view of the parts of my mechanism separated from each other and from the case-center. Fig. 2 is a like view of the same as combined for use. Figs. 3 and 4 are plan views of a watch, and show, respectively, the positions of parts when the stemoperated train is in engagement with the winding-wheel and with the dial-wheels. Fig. 5 is a perspective view of the case-center portion of my improvements as arranged for attachment to a hunting-case; and Fig. 6 is a like view of the same when in position within a case-center.

Letters of like name and kind refer to like parts in each of the figures.

My invention is an improvement in stem winding and setting watches in which the winding and setting train is placed in engagement with the winding-wheel or the dialwheels by the longitudinal movement of a rotatable stem arbor; and it consists, principally, as an improvement in stem winding and setting watches, in the combination of a rotatable, longitudinally-movable stem-arbor which has no positive connection with thewatch-movement, a device that is pivoted within the casecenter and adapted by a movement upon its axis to change the engagement of the winding and setting train from the winding-wheel to the dial-wheels, and an intermediate device which is contained within said case-center and is adapted to communicate the longitudinal movements of said stem-arbor to said pivoted device and cause the latter to turn upon its axis, substantially as and for the purpose hereinafter specified.

It consists further, as an improvement in stem winding and setting watches, in the combination of a rotatable, longitudinally-movable stem-arbor which has no positive connection with the watch-movement, a device that is pivoted within the case-center, and by a movement upon its axis is adapted to permit (Model) the winding and setting train to be disengaged from the dial-wheels and engaged with the winding-wheel, and an intermediate device which is contained within said case-center and is adapted to communicate the longitudinal movements of said stenrarbor to said pivoted device and cause the latter to turn upon its axis, substantially as and for the purpose hereinafter shown.

It consists, further, as an improvement in stem winding and setting watches, in the combination of a winding and setting train which is normally in engagement with the windingwheel, a device that is pivoted within the easecenter, and by a movement upon its axis is adapted to change the engagement of the winding and setting train from the windingwheel to the dial-wheels, a rotatable longitudinally-movable stem-arbor which has no positive connection with the watchmovement, and an intermediate device that is contained within said case-center and is adapted to communicate the longitudinal movements of said stem-arbor to said pivoted device and cause the latter to turn upon its axis, substantially as and for the purpose hereinafter set forth.

It consists, further, as an improvement in stem winding and setting watches, in the combination of a winding and setting train which is normally in engagement with the windingwheel, a device that is pivoted within the casecenter, and by a movement upon its axis is adapted to permit the winding and setting train to be disengaged from the dial-wheels and engaged with thewindingwheel, a rotatable, longitudinally-movable stem-arbor which has no positive connection with the watch-movement, and an intermediate device that is contained within said case-center and is adapted to communicate the longitudinal movementsof said stem-arbor to said pivoted device and cause the latter to turn upon its axis, substantially as and for the purpose hereinafter shown and described.

It consists, further, as an improvement in stem winding and setting watches, in a watchcase provided with a rotatable longitudinallymovable stem-arbor,a pivoted device which,by a movement upon its axis is adapted to change the engaement of the winding and setting train from the winding -wheel to the dial wheels,

and an intermediate device that is adapted to communicate the longitudinal movements of said stem -arbor to said pivoted deviee'and cause the latter to turn upon its axis, each of said parts being connected with said case and having no positive connection with the watch movement, substantially as and for the purpose hereinafter specified.

It consists, finally, as an improvement in stem winding and setting watches, in a watchcase provided with a rotatable longitudinallymovable stem-arbor, a cam, which is pivoted within the inner face of the case-center and has gear-teeth atone point upon its periphery, and a lever that is pivoted within said case center and has one end engaged by a peripheral groove in said stem-arbor and its opposite end,which is provided with a toothed seg ment, in engagement with the toothed periphcry of said cam, whereby alongitudinal movement of said stem-arbor will cause a partial rotation of said cam, substantially as and for the purpose hereinafter shown.

In the annexed drawings, A represents the center of a Watch-case which is provided with a stem or pendant, B, and has journaled within the same an arbor, O, that is rotatable in the usual manner, and is also adapted to have a certain amount of longitudinal motion. Within a groove, a, in the interior of the casecenter A, at one side of and preferably about one-half inch from the inner end of the stem.- arbor O, is pivoted a cam, D, which has the form shown in Figs. 1 and 2, and is provided upon its periphery at the point of its smallest radial dimensions with gear-teeth d. Within the groove a, between the stem-arbor O and cam D, is pivoted a lever,E, which, as seen in Fig. 1, has upon one end a toothed segment, e, that engages with the gear-teeth d of said cam, and at its opposite end e is adapted to fit into and engage with a peripheral groove, 0, which is formed within said stem-arbor near its lower end. If, now,the stem-arbor G is moved longitudinally within the pendant B, its motion in such direction will be communicated to the lever E, and through the same to the cam D, and will cause the latter to have a partial rotation upon its axis. Said parts are relatively arranged so that when said stem-arbor is at the outer limit of its motion said cam will have its largest portion turned inward toward the axis of the ease, as seen in Fig. 4, while by moving said arbor to theinner limit of its motion said cam will be turned outward to the position shown in Fig. 5. The case thus provided is intended for th reception of an ordinary watch-movement, F, in which the winding-wheel G and dial-wheels H are, when desired, connected with the stemarbor O, by means of a pinion, I, that is engaged by the inner end of said arbor, a gearwheel, K, which is journaled upon the movement plate and receives motion from said pinion, and two pinions, L and M, respectively, that are journaled upon a yoke, N, which is pivoted upon the axis of said wheel K. The

train is normally in position for winding the mainspring.

The movements of the cam D are utilized for changing the engagement of the winding and setting train from the winding-wheel to the dial-wheels by providing upon the end of the yoke N, adjacent'to the pinion M, an arm, n, which extends outward to position for engagement by said cam, the arrangement being such that an inward movement of said cam will turn said yoke to the position shown in Fig. 4 while, when said cam is moved outward said yoke will be'turned to the position seen in Fig. 3, by the operationof the spring 0.

The construction described is adapted for open-faced watch'cases. where the interior of the case-center A is provided with an annular recess, a, the cam D and lever E are pivoted upon a block, P, as shown in Fig. 5, which block is fitted to said recess a, and is preferably secured therein by means of screws, as seen in Fig. 6.

This improvement adapts the watch-case to receive any movement which is designed for it, and renders the insertion therein or removal therefrom of a movement as easy as would be the same operation in case of keywinding watches.

Having thus fully set forth the nature and merits of my invention, what I claim is- 1. As an improvement in stem winding and setting watches, the combination of a rotatable longitudinally-movable stem-arbor which has no. positive connection with the watch-movement, a device that is pivoted within the case center, and adapted by a movement upon its axis to change the engagement of the winding and setting train from the winding-wheel to the dial-wheels, and an intermediate device which is contained within said easecenter and is adapted to communicate the longitudinal movements of said stem-arbor to said pivoted device and cause the latter to turn upon its axis, substantially as and for the purpose specified.

,2. As an improvement in stem winding and setting watches, the combination of a rotatable longitudinally-movable stem-arbor which has no positive connection with the watchmovement, a device that is pivoted within the case-center and by a movement upon its axis is adapted to permit the winding and setting train to be disengaged from the dial-wheels and engaged with the winding-wheel, and an For hunting-cases,

intermediate device which is contained within said case-center and is adapted to communicate the longitudinal movements of said stemarbor to said pivoted device and cause the latter to turn upon its axis, substantially as and for the purpose shown.

3. As an improvement in stem winding and setting watches, the combination of a winding and setting train which is normally in engagement with the winding wheel, a device that is pivoted within the case-center and by a movement upon its axis is adapted to change the engagement of the winding and setting train from the winding-wheel to the dial-wheels, a rotatable longitudinally-movable stem-arbor which has no positive connection with the watch-movement, and an intermediate device that is contained within said case-center and is adapted to communicate the longitudinal movements of said stem-arbor to said pivoted device and cause the latter to turn upon its axis, substantially as and for the purpose set forth.

4. As an improvement in stem winding and setting watches, the combination of a winding and setting train which is normally in engagement with the winding-wheel, a device that is pivoted within the case-center and by a movement upon its axis is adapted to permit the winding and setting train to be disengaged from the dial-wheels and engaged with the winding-wheel, a rotatable longitudinallymovable stem-arbor which has no positive connection with the watch-movement, and an intermediate device that is contained within said case-center and is adapted to communicate the longitudinal movements of said stemarbor to said pivoted device and cause the latter to turn upon its axis, substantially as and for the purpose shown and described.

5. As animprovement in stemwinding and setting watches, a watch-case provided with a rotatable longitudinally-movable stem-arbor, a pivoted device which by a movement upon its axis is adapted to change the engagement of the winding and setting train from the winding-wheel to the dial-wheels, and an intermediate device that is adapted to co1nn1unicate the longitudinal movements of said stem-arbor to said pivoted device and cause the latter to turn upon its axis, each of said parts being connected with said case and having no positive connection with the watchmovement, substantially as and for the purpose specified.

6. As an improvement in stem winding and setting watches, a watch-case provided with a rotatable longitudinally-movable stem-arbor, a cam which is pivoted within the inner face of the case-center and has gear-teeth at one point upon its periphery, and a lever that is pivoted within said case-center and has one end engaged by a peripheral groove in said stem-arbor and its opposite end, which is provided with a toothed segment, in engagement with the toothed periphery of said cam,

whereby a longitudinal movement of said stemarbor will cause a partial rotation of said cam, substantially as and for the purpose shown.

In testimony that I claim the foregoing I have hereunto set my hand this 18th day of September, 1885.
